资源简介：
IGR Map - Global Topographic Relief, is a lightweight raster map showing the topography of the continents and oceans on the Earth. It is based on GEBCO Grid (retaining the same resolution) and processed with various terrain visualization techniques brought by FujiShaderGPU. The file is a Cloud Optimized GeoTIFF with JPEG tiles packed in a tiny 366 MB size, which allows a smooth viewing experience even on a low-end machine. The coloring aims to blend well with symbols so that it can be used as the basemap of figures.
